go banshee

To go ape shit on, or attack, someone - all while screaming.

Only women can go banshee, as the phrase is based on the female spirit in Irish mythology that has a high-pitched scream/wail. Banshees are said to wail around a house if someone inside is about to die.

Originated in La Mesa, CA.

- "When I found some other bitch's underwear in Ben's closet, I totally went banshee on him."

- "Yeah, she didn't get the promotion. I'm kind of afraid she's gonna go banshee."

Banshee Toast

In Halo 3, this is the result of what usually happens when a Banshee gets shot down with a Spartan Laser.

I flew the Banshee towards the other base and, as a result, I became Banshee Toast.

Banshee

A name for someone or something with a low-pitched and loud cry, moan or whimper coming from one whom is determined, frightened, devastated, etc.
